EC controller
Connecting the EC controller – example of a fan with MODBUS RTU compatibility
Stand-alone control device for refrigeration and air-conditioning technology in conjunction with the The EC controller functions as a stand-alone control device for fan networks in combination with external sensors. Factory default applications ensure
corresponding sensors. Using the controlled 0–10 V output or RS485 MODBUS RTU connection, easy commissioning – connecting a computer or other software-supported devices is not necessary. For programming new applications and for
ebm-papst fans with a corresponding input can be triggered. The function includes multifunctional monitoring, an integrated keypad control with LCD display replaces the external input devices.
pressure and temperature control as well as display and entry of various parameters. The integrated
LCD display provides easy operation across multiple levels. Note for large systems: After 31 fans, a repeater can be installed in order to connect another 31 fans.
